ACT as men of thought; THINK as men of action.

Life does not proceed by the association and addition of elements, but by dissociation and division.

It is of man's essence to create materially and morally, to fabricate things and to fabricate himself. Homo faber is the definition I propose ... Homo faber, Homo sapiens, I pay my respects to both, for they tend to merge.

In reality, the past is preserved by itself automatically.

I would say act like a man of thought and think like a man of action.

An absolute can only be given in an intuition, while all the rest has to do with analysis.

To exist is to change, to change is to mature, to mature is to go on creating oneself endlessly.
